DRIVING-CLUTCH.

Specification of Letters Patent. Patented Apr. 12, 1910- Applicationfiled June 1, 1909. Serial No.- 499,424.

To all whom it may concern:

Be it known that I, DANIEL S. BEARD, a citizen of the United States,residing at \Vaynesboro, in the county of Franklin and State ofPennsylvania, have invented certain new and useful Improvements inDriving-Olutches; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to driving clutches or couplings which slip anddisengage automatically when the load exceeds a prearranged amount; andit consists in the novel construction and combination of the partshereinafter fully described and claimed.

In the drawings, Figure 1 is a side view of the clutch with portions ofthe fly-wheel broken away. Fig. 2 is a longitudinal section, taken onthe line m-:v in Fig. 1. Fig. 3 is a detail view showing the teeth orserrations of the clutch members.

A is the shaft of a machine which is driven by means of the clutch. Thisshaft is preferably the driving shaft of a hay-baling press or othermachine in which the resistance is variable, and in which sudden andgreatly increased resistances occasionally occur.

B is a clutch-member rigidly secured on the shaft A by a key a andprovided with a disk havin teeth or serrations b on its face.

C is a y-wheel, the hub c of which is journaled to revolve freely on thehuh I) of the clutch-memberB.

D is a driving-pulley, or other equivalentdriving-device, which isrigidly secured to the fiy-wheel C, and which is driven from anengine'by means of a driving-belt in the usual manner.

E is a slidable clutch-member the hub e of which is slidable andrevoluble on the shaft A. The clutch-member E is provided with a diskhaving teeth or serrations 7 which are normally held in engagement withthe teeth 6.

G are driving-pins which are secured to the fly-wheel, and, whichproject through holes in lugs g on the clutch-member E.

H are springs arranged around the pins- G, and h are "adjusting. nuts.scre'wed on the free end portions of thep'ins and pressing the springsH against the slidable clutchmemoer E.

The power of the engine is applied to the fly-wheel by means of thedriving-pulley D, and when a sudden load comes on the shaft A of thepress or machine, the slidable clutch-member E is forced lon itudinallyof the shaft out of engagement with the clutchmember B, so that thefly-wheel continues to be revolved without causing any accident orinjurious strain to any part of the mechanism. The angle of the clutchteeth, and the pressure of the springs, are arranged and adjusted sothat the clutch-members are automatically forced out of engagement witheach other when the load on'the shaft A exceeds a prearranged amount.

'hat- I claim is:

1. The combination, with a revoluble shaft for transmitting power, and aclutchdisk rigidly secured thereon; of a fly-wheel journaled to revolveindependent of the said shaft and provided with means for revolving it,said fly-wheel being arranged to one side of the said disk, a slidableand revoluble disk provided with a hub on one side which is rigidlysecured on the said shaft; of a fly-wheel journaled loose on the saidhub and provided with means for revolving it, a slidable and revolubleclutch-disk journaled loose on the said shaft, and driving connectionsprovided with springs and arranged between the said fly-wheel and theslidable and revoluble clutch-disk, said springs operating to press thetwo clutch-disks together.

In testimony whereof I have aflixed my signature in the'presence of twowitnesses. DANIEL S. BEARD.
